I found something that works for me...
I found this thread while looking for an app to stream from my G300 to my TV through a DLNA certified LG bluray player. Unfortunately the link for the huawei app isn't working. I'm still on stock gingerbread for the time being so it wouldn't work on my phone anyway.
BUT here's something that works brilliantly... It's called SKIFTA. It claims to be DLNA certified and is really slick and simple to use. It's free and you can get it on Google Play, they also have a website. I've tried out at least a dozen other apps and not one worked properly for me, except Skifta. Now I can see my pictures on my phone on my TV and i can stream music and video. It even works with HD video.
Another potentially useful feature is the ability to connect to and stream from a range of cloud services such as dropbox,picasa,photobucket, internet radio etc. You can also access your home network remotely with your phone according to the website. I haven't tried these features yet though.
